[igt-dev] [PATCH v16 5/8] tests: gem_exec_basic: add engine discovery test

> The "exec-engines-ctx" and "exec-physical-engines-ctx" are two
> demo subtest inserted in the gem_exec_basic
> test. The main goal is to reach the engines by using
> the new uapi interfacing with 'gem_topology_has_engine()'.
> 
> The two cases get the list of both virtual and physical and only
> physical engines and makes sure they actually exist.

I'd say that is worth a little polishing on what the error might have
been.
